Lithium Ion battery

In 2006, D2 was asked to test laptop computer Li-Ion batteries to determine danger levels. The result was that batteries went into a thermal runaway state that culminated with a violent explosion. Ultimately, over 8 million batteries were recalled due to an alleged manufacturing defect.
Seven years later, D2 was asked to do a follow-up study to see if anything had changed.
